Description
An issue was discovered in ownCloud owncloud/graphapi 0.2.x before 0.2.1 and 0.3.x before 0.3.1. The graphapi app relies on a third-party GetPhpInfo.php library that provides a URL. When this URL is accessed, it reveals the configuration details of the PHP environment (phpinfo). This information includes all the environment variables of the webserver. In containerized deployments, these environment variables may include sensitive data such as the ownCloud admin password, mail server credentials, and license key. Simply disabling the graphapi app does not eliminate the vulnerability. Additionally, phpinfo exposes various other potentially sensitive configuration details that could be exploited by an attacker to gather information about the system. Therefore, even if ownCloud is not running
Informational only. Not a warranty of security, completeness or fitness for any purpose. Derived from NVD, CISA KEV, FIRST.org EPSS and vendor advisories (CVE Program List v5); those sources change continuously and may be incomplete or incorrect. Verify every remediation against the vendor advisory before acting. Absence of a finding is not evidence that no vulnerability exists. Not endorsed by NVD, CISA, FIRST or any vendor named.
